❓ Frequently Asked Questions
Q: Will this card work in a PCIe x16 slot?
A: Yes! This PCIe x1 card is fully compatible with x1, x4, x8, and x16 slots. You can install it in any available PCIe slot on your motherboard.
Q: Do I need to install drivers for Windows 10/11?
A: For optimal performance, we recommend downloading and installing the latest driver from our driver package.
Q: Can both ports be used simultaneously?
A: Absolutely! Both RJ45 ports can operate simultaneously at full 1000Mbps speed, making this ideal for network bridging, failover configurations, or connecting to multiple networks.
Q: Is the low-profile bracket included?
A: Yes! The package includes both standard and low-profile brackets, making it compatible with full-size towers and compact/slim cases.
Q: Does this support Linux?
A: Yes! The RTL8111H chipset has native support in most Linux distributions (kernel 2.6+). No additional drivers are typically required for Linux systems.
Q: What's the difference between this and onboard ethernet?
A: This card provides two additional gigabit ethernet ports, ideal when your onboard port fails, you need network redundancy, or require separate networks (e.g., one for LAN, one for WAN/management).
Q: Can I use this for link aggregation (bonding/teaming)?
A: Yes! This card supports network bonding/teaming in Windows, Linux, and other operating systems, allowing you to combine both ports for increased bandwidth or redundancy (requires switch support).
Q: Does it support jumbo frames?
A: Yes! This card supports jumbo frames up to 9K bytes (9000 MTU), which can improve network performance for large file transfers, especially in NAS and server environments.
Q: What power does this card require?
A: The card is powered entirely through the PCIe slot and requires no additional power connectors. It's energy-efficient and supports IEEE 802.3az Energy Efficient Ethernet (EEE).
Q: Is this suitable for virtualization environments (ESXi, Proxmox)?
A: Yes! The RTL8111H chipset is widely supported in virtualization platforms including VMware ESXi, Proxmox, and Hyper-V, making it excellent for homelab and enterprise virtualization setups.
